Question

what is the significance of meiosis in the context of evolution? a it produces identical offspring b it prevents genetic variation c it increases genetic diversity, allowing species to adapt and evolve d it reduces the number of mutations
during which stage of meiosis does crossing - over occur? a telophase i b metaphase i c prophase i d anaphase i
what is the primary purpose of meiosis in sexually reproducing organisms? a to increase the size of an organism b to repair damaged tissues c to produce diploid cells identical to the parent cell d to produce haploid gametes with genetic diversity
what is the significance of independent assortment in meiosis? a it produces diploid cells from haploid cells b it ensures that all chromosomes are identical c it increases genetic variation by randomly distributing chromosomes to gametes d it prevents genetic diversity in offspring
how many cells are produced at the end of meiosis? a four diploid cells b eight haploid cells c two haploid cells d four haploid cells
what is the final outcome of meiosis ii? a two identical diploid cells b four identical diploid cells c four non - identical haploid gametes d two non - identical haploid cells
what is the main event during metaphase i of meiosis? a sister chromatids are pulled apart b the cell divides into two haploid cells

Explanation:

1. Meiosis is a type of cell - division that produces genetic diversity. Crossing - over in prophase I exchanges genetic material between homologous chromosomes. Independent assortment in meiosis randomly distributes chromosomes to gametes, increasing genetic variation. The end result of meiosis is four non - identical haploid gametes.
2. During meiosis I, metaphase I is when homologous chromosomes line up at the equator, and anaphase I is when homologous chromosomes separate. Telophase I is the end of the first meiotic division. Prophase I is when crossing - over occurs.
3. The primary purpose of meiosis in sexually reproducing organisms is to produce haploid gametes with genetic diversity for sexual reproduction.
4. Independent assortment in meiosis increases genetic variation by randomly distributing chromosomes to gametes.
5. At the end of meiosis, four haploid cells are produced.
6. The final outcome of meiosis II is four non - identical haploid gametes.
7. In metaphase I of meiosis, homologous chromosomes line up at the equator of the cell.

Answer:

1. c. It increases genetic diversity, allowing species to adapt and evolve
2. c. Prophase I
3. d. To produce haploid gametes with genetic diversity
4. c. It increases genetic variation by randomly distributing chromosomes to gametes
5. d. Four haploid cells
6. c. Four non - identical haploid gametes
7. (No correct option fully described the main event of Metaphase I in the given options. But the correct main event is homologous chromosomes line up at the equator of the cell)
